I've just applied the latest patch for IE9 in Vista......now 9.1.8112.20557 and seem to be collecting a gathering of zombie installations with a limited threat rating as shown in psi....now 9 such examples.
It does'nt seem possible to remove them.....I don't wish to create an ignore rule for them.....are they all safe enough as is ? Are they likely to be removed at a later date anyrate ?

Your expertise would be very welcome Maurice, without being presumptuous ; if you would be so kind........regards.........

If I try to delete the items.....it says that I need permission......and then I get another panel saying Try Again which just repeats itself when pressed.
I've got an actual installation for 9.1.8112.20557
.............and then 8 Zombie files
C:\Windows\winsxs\x86_microsoft-windows-i..etexplo rer-optional-31bf3856ad364e35-(20554, 20553,20551,16450,16448,16447,16421,16446 version numbers )
Also :-
1 Zombie :-
C:\ProgramFiles\InternetExplorer\iexplore.exe,vers ion9.0.8112.16450

All the Zombie files are shown as Patched with a Very Limited threat rating

Yes...logged on as admin.
I'm just wondering that tho' psi has them showing as Zombie whether or not there's still a cumulative value to them and perhaps they're better left alone ?
As each successive update has taken place I'd kept thinking that MS would remove them if not required. I havn't developed paranoia.....I hope it's not me that's sleeping !!!

Thanks for your help and comments Maurice......appreciate your looking into the matter further.

Whilst on the main Scan Results page the installation is shown as 9.1.8112.20557......when clicking on the + sign.......in amongst the entries previously mentioned is the C:\ProgramFiles\InternetExplorer\iexplorer.exe,ver sion9.0.8112.16450

I think I have cracked it. The IMPORTANT bit is that if you have installed KB2744842 (the latest MS patch) IE on your PC is protected minus this http://secunia.com/advisories/47129/ which I consider unimportant & not relevant to IE9.

I think what you have found is an inconsistency on the way Secunia are now displaying IE.

I have tested the results shown by PSI on these PC's.

XP SP3 32 Bit using PSI version 1.5.0.2 - This merely confirms IE8 has only one entry in the Scan Result Page & is secure under version 8.0.6001.18702 minus this http://secunia.com/advisories/24314/

Have just completed a full scan using psi 2.0.0.3003......the situation has changed somewhat.

Clicking on the + sign on the Scan Results page and then double tapping brings up the entries where under the Classification heading the term Zombie Installation now only appears alongside 5 of the entries.
C:\ProgramFiles\InternetExplorer\iexploe.exe together with 4 previously rated Zombies are now showing as Actual Installations..................leaving still 5 entries as Zombie.
